We use the 800 or 820 transaxle with the spider gears locked and get along great. Some people run 600 but you gotta be able to shift it pretty well but not alot of guys run 700 series.

Ragb or horizontal motor with jack shafts that would be my first choice

Look up the youtube video of Sumner Mo lawn mower races and you will see the types of mowers our club runs. we run a stock mower class for kids and then kids super stock, adult super stock, modified and outlaws. We have never had good luck running a RAGB but in the outlaws class we have guys running commet clutches and jack shafts and those mowers will move in 160 ft track we race on.

Gary,

   By "TransMatic transaxle", I presume you are talking about the Vari-Drive movable-center pulley and 2-belt drive system, as well?

   In working on these mowers for many years, I've often thought about this but never attempted it.  If I was using this system, I would start with one from the larger MTD tractors that use the twin-cylinder engines (beefier Vari-Drive).  For minimal HP loss, I would:
1. Do away with the transaxle;
2. Rotate the entire pulley/belt system 90 degrees;
3. Run the rear belt directly to a pulley on a 1-piece rear axle;
4. Use a horizontal-shaft engine.
   This way, you only have two belts and three pulleys eating horsepower between the engine and the rear axle.
   Starting out in "low" should allow minimal belt slip, and moving the pulley clutchlessly into higher "gears" as you progress down the track should give you significant speed increases.

   Just my thoughts.

   Then again, it depends on what your rules allow...
